Conference Description

The Gordon Research Seminar on String Theory and Cosmology is a unique forum for graduate students, post-docs, and other scientists with comparable levels of experience and education to present and exchange new data and cutting edge ideas.

The focus of this meeting is the realization of cosmological spacetimes within string theory, describing both the early universe's inflationary phase, its matter content and late-time dark energy domination. A primary goal will be to understand constructions of and obstructions to de Sitter vacua in string theory.

Related Meeting

This GRS will be held in conjunction with the "String Theory and Cosmology" Gordon Research Conference (GRC). Those interested in attending both meetings must submit an application for the GRC in addition to an application for the GRS. Refer to the associated GRC program page for more information.
